FLUSHING APPARATUS.

Application mea January 22, 1921.

T 0 all w hom t may concern Be it known that I, W ILHELM WEBER, acitizen of the German Republic, residing at Wiesbaden, Germany, haveinvented certain new and useful Improvements in Flushing Apparatus (forwhich I have tiled an application for patent in Germany on the 21st ofMarch, 1918), of which the following is a speciication.

This invention relates to rolling flushing apparatus designed to loosenby flushing masses of sand and gra-vel and to conduct the same away fromthe workings.

The apparatus is preferably used where flushing dredgers with opengutters cannot be used as for example with specially high workings. Insuch a case the position of the gutter could be too steep so that thematerial obtained by flushing would flow over the gutter. Owing to itsmovability in many directions the device is particularly adapted tovFlush deep cuts into the earth and to get at any angle of the field tobe flushed.

The characteristic feature of the invention consists in the idea to usetelescopic pipes instead ot the open gutters used at present, saidtelescopic pipes having at the heads closed flushing tunnels withmovably spraying pipes for water under pressure. The device comprisestwo such heads arranged in U-shape it is movable in any directions andit is connected at the rear end with a closed conduit. In this mannerthe material obtained by flushing is conducted, directly at the placewhere it is obtained, by means of the flushing funnel which forms thehead of the flushing pipe, to a closed pipe system, whereby the liveforce of the flushed material is utilized for the further transport ofthe material ina better manner than with open gutters. Owing to the Ufshaped connection between the flushing heads the device can adapt itselfmuch better to the inequalities of the said heap .or incline, thegeneral moi/'ability oi the whole flushing device being ensured. Aclosed pipe conduit is arranged under the rolling and pivotablesupporting frame 'for the flushing dredger in such a manner that theconnecting pipe for the lusher heads can be connected in three positionsa, b and c, its general capability of being turned in all directionsbeing not impeded.

In order that the invention may be clearly understood, I shall proceedto describe the Serial No. 439,272.

same with reference to the example of construction shown in theaccompanying drawings, wherein Fig. l is an elevation of the flushingplant and Fig. 2 a plan view of the flushing pipes.

The iiushing plant consists of a fra-me which is mounted on wheels andarranged so that it Ican be p ivoted in horizontal direction. At thefront end of the frame two telescopic pipes a and Z are arranged whichare fixed u on a connecting piece in U-shape and which carry at theirfree ends flushing tunnels c which possess individual movability. Theseflushing funnels c can be brought, both together and the oneindependently from the other, by means of slewing arms d and ropes e, toany desired position. The flushing tunnels f are'directly in contactwith the sand heap to be worked, and arranged in such a manner, thatthey can take up a quantity of material which corresponds with theholding capacity of the flushing conduit and which can be regulated bythe grate g. A pipe It for lushing water under pressure is adjustablymounted in each flushing head f.

The working method is the same as with other plants used for the samepurpose.

The apparatus is mounted at the foot of a heap of sand or gravel andsupplied with water under a pressure of 2 to 5 atm. With the aid of thewater under pressure the sand is loosened by flushing and conducted tothe main conduit by means of the Hushing heads.

I claim l. An improved locomotive flushing apparatus for the obtentionof iiushing material from minings comprising in combination, a framemounted on wheels, an electrically operated slewing crane supported bysaid frame, a Hushing conduit under said frame, a U-shaped connectingpipe at the head of said flushing conduit, telescopic pipes in each armof said connecting piece, a funnel shaped head at the upper end of eachtelescopic pipe suspended to said slewing crane, a water pipe upon eachof said telescopic arms and a flushing nozzle of said water pipe in saidflushing head.
